DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shock-absorbing member, and more particularly to a structure in which a waterproof sheet is provided on a roof such as a building.
The present invention relates to a cushioning member for preventing the waterproof sheet from being broken.

[0002]

2. Description of the Related Art In a building without a roof, such as a building or a condominium, a rooftop portion serves as a roof. As shown in FIG. 7, the roof usually includes a roof floor 1 and an outer wall 2 surrounding the floor 1 and protruding upward to prevent the roof from falling down. In order to prevent rainwater from entering the inside of the building from the joint corner 3, a waterproof sheet 4 is put on the entire rooftop. In particular, when the prefabricated construction method is adopted, water leakage accidents at the connection between the floor surface and the rising portion of the parapet are extremely large, and the installation of the waterproof sheet 4 is indispensable. A pressing mortar layer 5 is formed on the waterproof sheet 4 for the purpose of pressing the waterproof sheet 4 and the like.

In a building or the like having such a roof structure, when the whole building is shaken by a large earthquake, the roof floor surface 1, the outer wall (parapet rising portion) 2 and the holding mortar layer, each of which is formed rigidly, are formed. When the members 5 swing independently, the waterproof sheet 4 in the vicinity of these joint corners 3 may be broken. Further, when the pressing mortar layer 5 expands and the waterproof sheet 4 is sandwiched between the outer wall (parapet rising section) 2 and strongly pressed, the waterproof sheet 4 at that location may be broken.

[0004] Therefore, as shown in FIG. 8 in order to prevent rupture of such a waterproof sheet 4, it is disposed a buffer member 6 has been proposed to the joint angle section 3. The cushioning member 6 is integrally formed in an L-shape using urethane rubber, expanded polystyrene, or the like. The elasticity of the cushioning member 6 absorbs vibration and pressing force, thereby preventing the waterproof sheet 4 from breaking.

[0005]

By the way, on the roof of a building or the like, as shown in FIG. 9 (a ), the center of the floor surface 1 is high and becomes lower toward the outer wall 2 so that rainwater does not accumulate . As shown in FIG. 3B, the floor 1 is configured to be lower from one outer wall 2 side to the other outer wall 2 side. For this reason, the floor surface 1 and the outer wall 2 are joined at an acute angle or an obtuse angle, and the cushioning member 6 provided at the joint corner 3 is formed at an acute angle or It is desirable that the angle is formed at an obtuse angle.

However, the joint angle between the floor surface 1 and the outer wall 2 varies depending on the builder or designer, and also varies depending on the rooftop use and is not uniform. Moreover,
Since this joining angle is made in the field, the angle varies depending on the location. Therefore, in order to prepare the cushioning member 6 which can be in close contact with the floor surface 1 and the outer wall 2, various types of cushioning members 6 having different angles are required, which not only requires the manufacturing cost but also the cost associated with the inventory. There was a problem. Further, there is a problem that the L-shaped cushioning member 6 is bulky and the transportation cost is high. Further, the urethane rubber cushioning member 6 is heavy, so that it is difficult to handle, and there is a problem that a portion that is erected along the outer wall 2 may fall down due to its own weight.

For this reason, the cushioning member 6 is formed at a right angle by using expanded polystyrene or the like, and is bonded to the floor surface 1 and the outer wall 2 with an adhesive. Or, it was used by being forcibly deformed to an obtuse angle. However, this work requires not only labor but also the deformed cushioning member 6 tries to return to the original shape by the member force, and the cushioning member 6 peels off from the surface of the floor surface 1 or the outer wall 2, There was a risk that the waterproof would be destroyed at that location.

The inventors of the present invention have conducted intensive studies to solve such problems, and as a result, have completed the present invention.

Particularly, the cushioning member formed of the foamed resin is easily cut, and after the cushioning member is adhered to the floor surface and the outer wall, the outer wall member having a large size is cut.

Further, a rib is formed on a contact surface of the outer wall member constituting the cushioning member, which is in contact with the outer wall, so that the amount of material used can be reduced while maintaining a predetermined strength.

[0019]

Next, an embodiment of a cushioning member according to the present invention will be described in detail with reference to the drawings. As shown in FIGS. 1 and 2, the cushioning member 10 includes a floor member 12 disposed on a rooftop floor side of a building or the like, and an outer wall member 14 disposed on an outer wall side surrounding the floor surface. The floor member 12 and the outer wall member 14 are integrally connected by an integral hinge 16.

The floor member 12 has a slope 20 inclined at an angle of less than about 45 degrees with respect to a plane 18 bonded to the floor, and the slope 20 has a rectangular surface shape and a triangular cross-sectional shape. A plurality of triangular prism-shaped recesses 22 are formed in a straight line, and the recesses 22 are formed in a shape that expands from the opening to the inside. On the other hand, the outer wall member 1
4 has a slope 26 inclined at an angle of less than about 45 degrees with respect to a plane 24 adhered or brought into contact with the outer wall, and the slope 26 has a triangular prism-shaped projection corresponding to the recess 22 of the floor member 12. A plurality of portions 28 are formed linearly,
The convex portion 28 is formed in a shape that widens from the slope 26 to the tip of the convex portion. Further, ribs 30 are formed on the outer wall member 14 on the side of the flat surface 24 as shown in FIG. 2 to maintain a certain strength and reduce the amount of material used.

Therefore, as shown in FIG. 3, when the concave portion 22 of the floor member 12 and the convex portion 28 of the outer wall member 14 are engaged with each other, the convex portion 28 having the widened distal end portion and the concave portion 22 having the internal widened portion. Are tightly engaged by a compressive force due to elastic deformation of the member, and stop at a predetermined angular position. When the concave portion 22 and the convex portion 28 are engaged,
The slope 20 of the floor member 12 and the slope 26 of the outer wall member 14 are combined so as to face each other. Since both the slope 20 and the slope 26 are formed at an angle of less than about 45 degrees, the two slopes 20 and 26 are in close contact with each other. In this case, the floor member 12 and the outer wall member 14 form an acute angle, as indicated by a dashed line in FIG. On the other hand, when a gap is formed between the two slopes 20 and 26, as shown by a solid line or a two-dot chain line in FIG.

Further, as shown in FIG.
When the outer wall member 14 and the outer wall member 14 are combined, the inclined surface 32 is formed on the inner surface side of the joint portion between them, and the same inclined surface 34 is formed on the outer surface side. The slope 32 on the inner surface side is for preventing the waterproof sheet from being broken at the corners when the waterproof sheet is laid. On the other hand, the slope 34 on the outer surface side avoids the mortar or the like applied to the joint between the floor surface 36 and the outer wall 38, and makes the floor surface member 12 and the outer wall member 14 adhere to the floor surface 36 and the outer wall 38, respectively. is there.

The floor member 12 and the outer wall member 1 of the cushioning member 10
4 is connected by the integral hinge 16 at the tip of each of the slopes 20 and 26, as described above. The integral hinge 16 is formed integrally with the floor member 12 and the outer wall member 14 so that the integral hinge 16 is thin enough to be flexible at the same time. Here, the cushioning member 1
0 is preferably formed of a foamed resin, for example, foamed polystyrene resin, foamed polyolefin resin such as foamed polyethylene or foamed polypropylene, foamed resin made to foam a copolymer of styrene and ethylene or propylene, or the like. It is preferably used, and is preferably formed by a bead forming method. In the case of the bead molding method, two or more kinds of beads may be mixed and molded, and it is preferable that the molding is performed by appropriately setting an appropriate expansion ratio in terms of strength. In the case of the bead molding method, it is possible to mold the integral hinge 16 having higher strength by performing mold clamping (cracking closing).

The cushioning member 10 having such a configuration is manufactured and shipped in an unfolded state as shown in FIGS. At this time, since the cushioning members 10 are stacked in a plane, they do not become bulky. As shown in FIG. 4, the cushioning member 10 carried into a building site such as a building or a condominium is attached to a place where a floor surface 36 and an outer wall 38 are provided outdoors such as a rooftop or a balcony. As described above, first, the floor member 12 and the outer wall member 14 are bent around the integral hinge 16 to attach the buffer member 10 to the recess 2.
2 and the projections 28 are engaged with each other, and then an adhesive is applied to the plane 18 of the floor member 12 and / or the plane 24 of the outer wall member 14 so that the floor member 12 and the outer wall member 14 are respectively bonded to the floor surface 36.
And adhere to the outer wall 38 in close contact. As the adhesive, an adhesive which is insoluble in water or the like after curing is used among solvent-based adhesives and aqueous adhesives. The cushioning member 10 is attached to the entire periphery along the outer wall 38, and the outer wall member 14 protruding from the end of the outer wall 38 is cut along the end of the outer wall 38 by a cutter or a heating wire.

A heat insulating material 40 is laid on the floor surface 36 of the cushioning member 10 which is not covered by the floor member 12.
Further, a waterproof sheet 42 is laid so as to cover the cushioning member 10 and the heat insulating material 40. A fixing member 44 for fixing the waterproof sheet 42 and the cushioning member 10 is provided at an end portion of the outer wall 38, and the floor surface member 12 of the cushioning member 10 on the floor surface 36 is provided on the floor surface 36 as necessary. Then, a pressing mortar 46 for pressing the heat insulating material 40 and the waterproof sheet 42 is driven, and the waterproofing work is completed.

As described above, the mounting work of the cushioning member 10 according to the present invention can be easily performed, and after the mounting, the cushioning member 10 can be mounted.
Since the internal stress does not remain on the outer wall 38, the cushioning member 10 does not peel off from the outer wall 38 or the like.

Although the embodiment of the cushioning member according to the present invention has been described in detail, the present invention is not limited to the above-described embodiment, but can be implemented in other modes.

For example, in the above embodiment, the concave portion 2

And rainwater is prevented from entering the interior through the recess 78 during installation work.

As described above, various embodiments of the cushioning member according to the present invention have been described with reference to the drawings. However, it is obvious that the present invention is not limited to these embodiments. For example, since the integral hinges 16 and 64 particularly require flexibility, only the integral hinges 16 and 64 are different from the outer wall members 14 and 60 and the floor members 12 and 62 in flexibility and viscosity. Alternatively, it may be formed by a partial two-layer forming method using a material having excellent elasticity and the like. Further, the integral hinges 16 and 64 may be configured by sticking a cloth or the like, for example, and it is not always necessary to integrally form the cushioning member with the same material.

Further, by forming a rib on the contact surface of the outer wall member which comes into contact with the outer wall, the material can be saved. However, the rib may be omitted, and the thickness of the outer wall member and the floor member is particularly limited. It is not limited. In addition, when the outer wall member and the floor member are engaged with each other, a buffer member may be attached to a gap formed in the engaging portion, and then the filler may be filled to close the gap. The present invention can be embodied in various modified, modified, and modified embodiments based on the knowledge of those skilled in the art without departing from the spirit of the invention.
